Deoxyribonucleic acid DNA is the blueprint for all inherited characteristics in living things. It is a very long sequence, written in code, that needs to be transcribed and translated before a cell can make the proteins that are essential for life. Any sort of changes in the DNA sequence can lead to changes in those proteins, and, in turn, they can translate into changes in the traits those proteins control. Changes at a molecular level lead to microevolution of species.

This effort will study and compare the DNA of other organisms to further our understanding of the human genetic makeup. This unique idea originated shortly after the United States developed and used the atomic bomb. Analysis of the oldest sedimentary rocks provides evidence for the origin of life List the atmospheric gases believed to have existed on early earth The atmospheric gases believed to have existed on early earth are: water vapour hydrogen methane ammonia Describe the hypothesised conditions and environment of early Earth Early Earth is predicted to have been a very hostile environment.
Asked by Wiki User. DNA may be packed differently or may contain additional chemical groups attached to the bases like methylated DNA. However, the structure of DNA is similar in all organisms. This is the reason why it has been named the molecule of life.
